Bottled once a year, only in the spring, it is sold as a limited edition bitters. Fee Brothers Orange Bitters aged in oak barrels once used to age Old Tom Gin to produce a mellow cooked orange aroma with delicate caramel notes and some warm spice including juniper. Barrel-Aged Orange Bitters is used by craft-cocktail mixers to elevate classic drinks such as an Old Fashioned and a Manhattan, and can be added to Champagne Cocktails or a Hot Toddy. This is a 150 ml bottle.
